Main technical characteristics

1. The overall investment in the province, including mechanical equipment, self -control electrical systems, civil construction and land acquisition fees;

2. The area covers a small area and is usually 1/5-1/10 of the area of conventional treatment technology. The factory area is compact and beautiful;

3. The quality of the water out of the water can meet the standard of water quality or mixed water quality standards;

4. The process process is short, the transmission efficiency of oxygen is high, the energy consumption of gas supply is low, and the power consumption of the unit sewage is low;

5. The filtration speed is high, and the processing load is much higher than the conventional processing process;

6. Strong resistance to impact, which is smallly affected by climate, geology, and water quality changes. It is particularly suitable for cold weather areas and can be intermittent.

7. It can be built to build a closed plant to reduce the impact of odor and noise on the surrounding environment. The visual sensory effect is good;

8. It is convenient for operation management and easy maintenance;

9. All modular structures are facilitated for later transformation and expansion.
